The Mathematical Works of Archimedes of Syracuse bc Home Online Articles Links ... Recommend a Friend While historians of mathematics generally consider Archimedes to have been one of the greatest ever mathematicians, in his own time he was probably better known for his practical achievements: the Archimedean screw, the compound pulley, the laws of leverage and his ‘engines of war’. We, however, will be concerned with his mathematical works, which cover a wide variety of topics. In On Spirals, Archimedes was interested in various areas, lengths and tangents associated with what are now called ‘Archimedean spirals’. One theorem shows that the circumference of a circle has the same length as a certain straight line associated with a tangent to his spiral. An Archimedean spiral can also be used to trisect the angle. The Measurement of the Circle , Archimedes showed that the area of a circle of radius R and circumference C is equal to that of a right-angled triangle, where the sides containing the right-angle are of lengths R and C. Combined with the above result from On Spirals , this effectively reduced the problem of squaring the circle to that of finding a particular tangent to the Archimedean spiral. By considering polygons (of 96 sides) inscribed and circumscribed about a circle, Archimedes also showed, in modern terms, that 3

The Production of Electricity by a Generator Driven by a Buoyancy engine by denis alan de Shon 7242 Seven Oaks Avenue Baton Rouge, LA 70806 majden@cox.net Working Title : Buoyant Power, My name is denis alan de Shon; I'm a researcher for Advanced Consulting Group in Baton Rouge, Louisiana. I had been researching the works of Archimedes of Syracuse and other Greek Natural Philosophers when I saw a means for employing Archimedes' findings in an engine to produce electricity, This is accomplished by the introduction of excess pressurized gases from industry, both compressed air as well as compressed petroleum gases, into a buoyancy engine which turns a generator to produce electricity from the latent power in relatively low power compressed gases. Here's a brief History of Buoyancy. Archimedes of Syracuse was a Genius Greek Mathematician and Natural Philosopher. Recall, he's the one who jumped out of his tub at the Syracuse Baths and ran naked toward his home shouting "Eureka, Eureka" (I Have Found). In his bath, he realized that the mass of his body disposed in the tub displaced a certain amount of water.

Who Was Archimedes? Infinite Secrets homepage Archimedes of Syracuse was one of the greatest mathematicians in history. He was also a great inventor and scientist. Most of what we know about Archimedes today comes from his writings and those of his contemporaries. Born in Syracuse, Sicily (then part of Greece), in about 287 B.C., Archimedes traveled to Egypt at the age of 18 to study at the great library of Alexandria. Upon completing his studies, he returned to Syracuse, where he spent the remainder of his life. Archimedes was obsessed with mathematics. He would become so involved in his work that he would forget to eat. He scribbled notes and figures on any available surface. When outside, he used a stick to draw on the ground; when inside, he used his finger to trace figures in the olive oil on his skin. Out of this obsession came many of his greatest theories and proofs, such as the means for approximating square roots, the value of pi (the ratio of a circle's circumference to its diameter), and the creation of a way to describe very large numbers. He also devised methods for calculating areas and volumes 2,000 years before the invention of calculus. In addition, Archimedes proved that the volume of a sphere is two-thirds the volume of a circumscribed cylinder. He considered this proof his greatest accomplishment and even requested that a representation of a sphere inside a cylinder be inscribed on his tomb. Archimedes was well known for his inventions and scientific discoveries. The most famous of these were the Archimedes' Screw (a device for raising water that is still used in crop irrigation and sewage treatment plants today) and Archimedes' principle of buoyancy. Legend has it that he discovered this principle while in the bath, where he noticed that the more of his body he submerged in the water, the greater the amount of water that over-flowed the bath. Upon making this discovery, he is said to have run naked through the streets of Syracuse, shouting "Eureka!" (Greek for "I have found it!").

UGESEDDEL 10 Afleveringsopgave til uge 46 Med venlig hilsen Brian Bech Nielsen Archimedes of Syracuse (ca. 287-ca. 212 BC) Greek mathematician who flourished in Sicily. He is generally considered to be the greatest mathematician of ancient times. Most of the facts about his life come from a biography about the Roman soldier Marcellus written by the Roman biographer Plutarch. Archimedes performed numerous geometric proofs using the rigid geometric formalism outlined by Euclid, excelling especially at computing areas and volumes using the method of exhaustion. He was especially proud of his discovery for finding the volume of a sphere, showing that it is two thirds the volume of the smallest cylinder that can contain it. At his request, the figure of a sphere and cylinder was engraved on his tombstone. In fact, it is often said that Archimedes would have invented calculus if the Greeks had only possessed a more tractable mathematical notation. By inscribing and circumscribing polygons on a circle, for instance, he was able to constrain the value of (pi ) between 3 10/71 and 3+1/7. Archimedes was also an outstanding engineer, formulating Archimedes' principle of buoyancy and the law of the lever. Legend has it that Archimedes discovered his principle of buoyancy, which states that the buoyancy force is equal to the weight of the liquid displaced, while taking a bath, upon which he is supposed to have run naked through the streets of Syracuse shouting "Eureka!" (I have found it). Archimedes is also purported to have invented the Archimedean screw. Some of Archimedes's geometric proofs were actually motivated by mechanical arguments which led him to the correct answer. During the Roman siege of Syracuse, he is said to have single-handedly defended the city by constructing lenses to focus the Sun's light on Roman ships and huge cranes to turn them upside down. When the Romans finally broke the siege, Archimedes was killed by a Roman soldier after snapping at him "Don't disturb my circles," a reference to a geometric figure he had outlined on the sand.

Young Archimedes is faced with great changes when he is sent to study in Alexandria. Times at home in Syracuse are unstable, but the sciences and arts flourish in the Greek metropolis in Egypt. The youth, brought up in sheltered circumstances, finds that travel broadens the mind - in the Mediterranean of Antiquity even more wildly than today. Archimedes is lucky to acquire a travelling companion, a mercenary who has lived life to the full, and his slave girl provides the mind of the mathematical genius with matters to mull over other than calculations.

Archimedes In the very long line of Greek mathematicians from Thales of Miletus and Pythagoras of Samos in the 6th century BC to Pappus of Alexandria in the 4th century AD, Archimedes of Syracuse (287 - 212 BC) is the undisputed leading figure. His pre-eminence is the more remarkable when we consider that this dazzling millenium of mathematics contains so many illustrious names, including Anaxagoras, Zeno, Hippocrates, Theodorus, Eudoxus, Euclid, Eratosthenes, Apollonius, Hipparchus, Heron, Menelaus, Ptolemy and Diophantus. (See the St Andrews archive History of Mathematics for information about these mathematicians.) Discoveries and inventions Although his main claim to fame is as a mathematician, Archimedes is also known for his many discoveries and inventions in physics and engineering, which include the following. His invention of the water-screw, still in use in Egypt, for irrigation, draining marshy land and pumping out water from the bilges of ships. His discovery of the hydrostatic principle that a body immersed in a fluid is subject to an upthrust equal to the weight of fluid displaced by the body. This discovery is said to have inspired his famous cry "Eureka" ("I have found it"). Mathematical achievements Before discussing the work covered in his book Measurement of the Circle , we mention briefly a few of the other significant contributions which Archimedes made to mathematics.

Know the mathematicians Leonard Euler (1707 – 1783) Leonard Euler (whose name rhymes with boiler not ruler). Astonishingly prolific, Euler created a body of mathematics whose sheer volume defies belief. But what endears him to his successors is not so much the mass of his writings as their richness, beauty, and penetrating insight. Euler produced nearly 900 treatises, books, and papers. It is estimated that he published an average of 800 pages of new mathematics per year over a career that spanned six decades. In all of history, no mathematician has bee able to think that fast; for that matter, most people can’t even write that fast. Starting in 1911 scholars began to publish Euler’s collected works under the title Opera Omnia. Today there are well over 70 volumes on the shelves and new ones will appear sporadically well into the twenty-first century. As a typical volume runs to 50large pages and weighs about 4 pounds, the overall bulk of his Opera Omnia stands at more than 300 pounds! Euler was born in Basel, Switzerland, in 1707. While still an adolescent he studied with Johann Bernoulli at a time when the latter was recognized as one of the world’s great mathematicians. During 1727 Euler, barely 20, travelled to Russia to assume a chair in the recently founded St. Petersburg Academy. There he remained until 1741, when an offer from the Berlin Academy of Frederick the Great proved more attractive. For a quarter of a century, Euler worked at the German Academy, where he overlapped such notables as d’Alembert, Maupertuis, and Voltaire. Then in 1766 he returned to St. Petersburg for good. Euler died there in 1783, still scientifically active at the age of 76.
